Quantum phase transition from a paramagnetic Anderson insulating state to a ferromagnetic many-body localized state via an intermediate ferromagnetic metallic phase
Kyung-Yong Park, Iksu Jang, Ki-Seok Kim
Effects of electron correlations on Anderson insulators have been one of the central themes for recent two decades, suggesting that the Anderson insulating phase turns into a novel…

General properties of fidelity in non-Hermitian quantum systems with PT symmetry
Yi-Ting Tu, Iksu Jang, Po-Yao Chang +1
The fidelity susceptibility is a tool for studying quantum phase transitions in the Hermitian condensed matter systems. Recently, it has been generalized with the biorthogonal basi…
